The present invention embodies novel structural featureswh-ereby greater du ra bil ity, efficiency and easeof operation may be had than heretofore.

In order that the invention maybe fully understood; reference will now be made to the accompanying drawings, in which:

it may be adjusted radially toward and away from the center of the large friction .wheelfi to drive the same at different speeds.

Adjustment of the small friction wheel 7 longitudinally vof/ the shaft 8, is efiected by a lever 10 having a bifurcated end 11 connected; by pivots 12, to dia metrieally opposite sides of'a collar '13, looselyembracingthe hub 14 of, the small friction wheel 7.

Specification ofLettersPatent. Patented Sept. 1917 The lever. 10 is fulcrumed upon a pivot 16- secured-to a bracket 17, which has a notched segment 18 to receive a latch 19-mounted on the lever 10 to lock the same in any-of its adjusted positions: l v

The bracket 17, isifixe'd at its bifurcated forwardend to a slidable frame 21, from one side of;- which the bearing 4: projects, so that said, bearing 4, together with the reel 2, will be: carried upand do-wn'hy said slidable frame- 21;

22 designates two pairs of threaded into unions 23, threaded upon the adjacentends of-braces' 24, extending through the upper and lower portions of the frame 21 and secured at their opposite ends to a circular flange 20, integral with the bearing 4. Each pair of pins 252 is provided with a transverse member 25, slidablethereon and provided with a cenftrallydisposedbushing- 26 slid-e ably mounted upon theshaft 8, but caused to rotate therewith. The transverse members 25 support the ,upper portion of the. a shaft 8' and are yiel'dingly-forc'ec'l by coil springs 27 toward the ,l;arg'e friction whefel 6, to holdthe small friction wheel 7 firmly! in frictional engagement therewith to rotate the same; The springs-27 are tensioned by screws 28 on the threaded endsof the pins" 22,.to regulate[the pressure of the small friction wheel 7 a ainst the'lar' e friction V b b up and down-bye long lever 30, fulcrumed upon a pin 31 extendingthrough a pair oflinks 32; mounted at, their lower ends upona pivot 3 3 projecting; from a notched s eg.- ment 34secure'd by U- bolts 35 to a portion of: the 1. g The forward portion of-th-e ,lever 30 is bifurcated as indicated at 36,

Fig. ,6, and one branch of said bifurcated portion. is connected by a pivot, 3-7 to the 'slid'able' name 2 h le the oth r branch is connected by a pivot 38 to the flange on the outer end of the bearing 4'to aid in supportingsaid-bearing.

The slidable frame 21 is locked at any point of its adjustment on the bifurcated member 29"by a latch 39 (Fig.2) ,consisting of two parallel members 40 united by trans-. verse me'mbers40 carried by the members 40, two latch pins 41 and a coil spring 42. Theparallel members 40 extend through the upper portion of the slidable frame 21 'normallyheld in the position disclosed' by Fig. 2, by .thespring 42 in order'to retain the "latchpins 41in notches 43 in the bifur-' in which they are operably-mounted and are ca'ted member 29. The parallel members 40 are. retracted. against the action 1 of the spring42 to disengage the latch 'p1ns'41 from the notches 43, by a rod 44 connected at its forwardend tosaid latch 39 and at its: rear end to a handle 45 slidable in a support 46 fixed to one side; of the lever 30, which Y is provided with a laterally projecting han-' dle 47,'adjacent said handle 45;

The bifurcated member 29 is pivotallymounted at its lower end upon ashaft 48, journaled in a bearing 49 carried by a U- bracket 50 secured by U-bolts 51 to a portion of the'frame 1.1 A lubricant chamber 52 is provided in the "bearing 49 for holding a suitablelubricant for the shaft 48. Said shaft 48 is-driven by-a sprocket wheel 54,

1 which-in turn is driven from asuitable part ofsthe'binder. I

Bevel gears155 and 56 fixed to the shafts 8 and 48, respectively, serve to transmit motion: from the latter toftheformer. As disclosed by Fig.8, the lower end of the shaft 8 is journaled in a U-bearing 58, one end of The lever 30 is normally locked from which'is fixed to the lower end of the bifurcatedmember 29, while its opposite end is rockable on the shaft 48.

backward or forward movement by alatch 60, adapted to engage the notched sector 34 and controlled by'fa handle '61,rods 62 and,

63; and a bell-crank 64 fulcrumed on the i i pin 31.

. The "operation briefly stated is as follows: The reel is adjusted up or down according to the height of thegrain, byrocking the lever 30 on the pivot 31, as'indicated by the been disengaged fromthe sector 34. An

desired speed is imparted to the reel by adjusting the small friction wheel 7 closer to or farther from the center of the large fric tion wheel 6, through the intermediacy of *arrow a, Fig. 1. Likewise the reel 2 may befadjusted forward or backward, as indicatedby the arrows b, Fig. 1, tosuit the condition of the grain by moving the lever 30 backward or forward after the latch 60 has the-lever 10.
